Abstract
In a data processing system having a plurality of resources and plurality of partitions, each partition including one or more resources of the plurality of resources, a method includes receiving an access request to a target resource of the plurality of resources; using a first set of transaction attributes of the access request to determine a partition identifier for the access request in which the partition identifier indicates a partition of the plurality of partitions which includes the target resource; using the partition identifier to determine access permissions for the partition indicated by the partition identifier; and based on the access permissions, determining whether or not the access request is permitted.
